Ill-tempered delinquent Kylie Bucknell is forced to return to the house she grew up in when the court places her on home detention. Her punishment is made all the more unbearable by the fact she has to live there with her mother Miriam. Unable to go beyond the front gate, she's forced to wait hours on end to use the telephone while listening to her mother's ludicrous theories that the house is haunted.

Kylie initially dismisses her mother's superstitions as nothing more than a conscious distraction from a life occupied by boiled vegetables and small-town gossip. However, when she too becomes privy to unsettling whispers, strange bumps in the night and a creepy teddy with a penchant for inappropriate small talk, she begins to wonder whether she's inherited her mother's overactive imagination, or if the house is in fact possessed by a hostile spirit who's not particularly thrilled about her return.

Help comes in the form of Kylie's ghost-obsessed home detention security guard Amos who regards paranormal matters with the casual grace of a plumber diagnosing a leaky pipe. Together they begin to unravel the secrets that lie within the walls. As the mystery unfolds, Kylie is drawn into a tangle of terror that forces her to reevaluate her belligerent behaviour as well as her fractured relationship with her mother.
